The closure can then be moved outwardly, or to the left as indicated in Figure 7, so as to pass the portions 28-28 through the elongated part of the slot. The extent of this movement is limited by engagement of the parts 24 and 2|.

The closure may then be lowered, the extensions 23 then passing down outside the portions the slot and when moved downwardly to engage with the reflector carried member at the ends of the lower portion of the slot and support the weight of the closure when open, the narrow portion of the support engaging the bottom of the slot to support the closure when swung to closed position.

2. A lighting fixture as claimed in claim 1, wherein the lower edge of the elongated member on the reflector is engageable with the upper face of the support to align the upper end of the support opposite the upper portion of the slot and facilitate insertion of the support through the slot.

3.A lighting fixture as claimed in claim 1, the frame and reflector having elements which, when the frame is swung away from the vertical position,"interengage and prevent lifting the of the bracket 16 and coming against the shoulj ders 30 provided by the offsetting of the portion 2| of the bracket I6. At this time the weight of the closure can be taken by the reflector and the closure can hang free as indicated in Figure 8 or the dot and dash position of Figure 2.

Thereafter, the closure can be moved back and forth between closed and open positions, as desired. When it is in the closed position the parts are located as indicated in Figures 4 and 9. The width of the closure is such that when it is moved up in place, the flange 2 2 on the closure is pushed out tightly against the flange Mon the reflector and the curving portion 26 of the closure brack ets 24 will cause theclosure to move upwardly and outwardly so that the closureis pushed up into position with its lower face substantially flush with the lowerface of the outer flange IS.

The brackets carried on the reflector are small and inconspicuous and-may be provided on reflectors irrespective of whether or not closures are to be supplied later. This makes it possible to employ the same reflectors in open fixtures and in fixtures having closures and to supply closures of any desired type which will fit the reflectors. The entire assembly and disassembly of parts can be accomplished without any tools whatsoever. Furthermore, th same structure using a single bracket on the reflector and a single bracket on the closure may beernployed as a hinge in annular lightingequipment,

Since it is obvious that the invention may be,

embodied in other forms and constructions within the scope of the claims, I wish it to be-understood that the particular form shown is, but one of these forms, and various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.

What is claimed is: H 1 1. A' lighting fixture having areflector. carrying a pendent elongated memberprovided with a horizontally elongated slot longer at the top than at the bottom, theportions of theimember..form-.

ing the ends and top .of the slot. being in one plane, the portion forming-the bottom of the slot being in an outwardly offset parallel plane, and

a reflector closure having a frame which is hori-..

zontal when the closure is closed and vertical when open, and .a support secured to the .inner face of the frame, the support extending lateral ly from the frame and curving upwardly and outwardly through substantially 90, and having its upper portion re-entrant .and longer than. the curving portion, th curving'portion being narrower than the lower portion of the slot,'the longer portion being ofv a length to passoutward- 1y laterally through the longer portion only of frame upwardly to place the elongated portion of the support opposite the elongated portion of the slot.

4. A lighting'fixture as claimed in Claim 1, wherein the reflector has a horizontal flange immediately above the elongated member and the frame has a peripheral flange extending at right angles to it, the width of the second flange being such that it swings underneath the reflector flange, the second flange being cut away to accommodate the elongated member.

.5. A reflector having an outwardly extending flange with a downwardly. facing seat, an elongated angle member of right angle cross-section having an upper portion extending lengthwise of the seat and secured to it and a lower portion extending downwardly from the seat, the lower portion having a slot, the material forming the lower wall of the slot being out of the plane of the material forming the upper part of the slot, the slot being elongated and longer at the top than the bottom, and a reflector cover having a supporting member having a narrow lower portion and an upper long portion, the longer portion being movable transversely through the upper part of the slot and downwardly behind the end walls of the narrower portion of the slot.

6. A lighting fixture having a normally horizontal fixed member forming a framed opening and having a pendent fixed sheet metal bracket extending lengthwise thereof and a lengthwise extending slot with a narrow lower portion and upper portion elongated in both directions, the bottom wall of the slot being displaced laterally to provide upwardly facing shoulders, and a movable closure having a sheet metal bracket fixedly secured to it, the portion of the bracket adjacent the movable member being of a length slightly less than the length of the shorter portion of the slot and extending through an; angle of substantially the portion of the bracket therebeyond having a length greater than the spacing of the shoulders and less than the length of the-longer portion of the slot, and extending back toward the closure member, the longer portion of the second bracket being insertabl-e through 'the longer portion of the slot only when, aligned therewith and normally resting on the shoulders. 7. A lighting fixture having a horizontal frame with a horizontal seat and depending outer wall to form a framed opening, and a closure having a peripheral band of right angle cross-section and slightly smaller than the opening in the frame, the frame carrying a longitudinally extending member below the seat and spaced from its, depending wall, the outer wall of the band being cut away opposite the frame carried memher, the other wall of the band opposite the cut away portion of the outer wall thereof carrying a bracket, the frame carried member having a slot with a long upper portion and a shorter lower portion, the bracket on the closure having an upper portion longer than the lower portion and insertable through the upper portions of the slot, and a narrow lower portion receivable in the lower portion of the slot.

8. A hinge mechanism comprising a fixed horizontal member having a downwardly facing seat and a downwardly extending flange, a door member which when closed has a horizontal upwardly facing band and an upwardly extending flange receivable inside the flange of the fixed member, the flange on the door member having a cut-out portion, the band carrying a hook member opposite the cut-out portion, the hook member being elongated but shorter than the cut-out portion and having its lower portion secured to the band and spaced from the flange, the hook member extending upwardly and outwardly to have its free end enter the space provided by cutting out the flange, the free end having extensions so as to be longer than the 25 attached end, the fixed member carrying a depending member having a slot with a lower pore tion through which the shorter portion of the 20 Number wardly on the extensions as pivots, and when pendent being movable upwardly to bring the extensions opposite the longer portion of the slot so that they may be moved through the slot to permit removal of the door.
